preparation example Construction

[0018] According to the present invention, the preparation method of the complex containing ruthenium comprises the following steps:

[0019] (1) In the mixed solution of liquefied ammonia and lower alcohol, aromatic hydrocarbons are mixed with alkali metals to obtain dihydroaromatic hydrocarbons;

[0020] (2) contacting the dihydroaromatic hydrocarbon with the ruthenium halide in the first organic solvent, and the conditions of the contact reaction make the reaction obtain the ruthenium halide arene dimer;

[0021] (3) The ruthenium halide arene dimer that step (2) obtains is contacted with the chelating ligand that contains two coordination atoms in the second organic solvent, and the chelating ligand that contains two coordination atoms is selected from From one of alkyldiamine, 8-hydroxyquinoline and its derivatives, and phenanthroline and its derivatives, the conditions of the contact reaction make the ruthenium in the ruthenium halide arene dimer and the two in the chela...

Abstract

The invention relates to a ruthenium-containing coordination compound. The ruthenium-containing coordination compound is a coordination compound expressed by ARu(X'Y')Z or [ARu(XY)Z]+B-, wherein A is arene; XY is one of dialkyl amine, and feiluolin and derivatives thereof; the X'Y' is one of 8-hydroxyguinoline and a derivative thereof; Z is one of halogen, -SCN, -N3,-SCH3, -SH, -COOH, pyridyl, pyridyl substituted by one or more groups in C1-C3 alkyl and tyrosine kinase inhibitor with a single coordination atom; and B- is PF6- or BF4-. The new ruthenium-containing coordination compound can effectively act on DNA, or substitute a high-selectivity protein kinase inhibitor or a derivative thereof for one or more of ligands in the cytotoxicity organic metal ruthenium coordination compound, and can act on the protein kinase (or protein phosphatase) and a multi-target point combining molecular anti-tumor compound of DNA at the same time.

Description

technical field [0001] The invention relates to a complex containing ruthenium and a preparation method thereof. Background technique [0002] Since the first report in 1969 that cisplatin (Cisplatin, also known as cisplatin) has a strong inhibitory effect on animal tumors, scientists have paid more attention to the anti-tumor research of metal complexes. In recent years, it has been confirmed that in addition to platinum, complexes such as ruthenium, rhodium, gallium, germanium, and tin also have anti-tumor activity, and the inhibitory activity of organometallic ruthenium complexes on ovarian cancer, non-small cell lung cancer and other cancer cells is comparable to that of cisplatin , and has no cross-resistance with cisplatin, and has low toxicity and side effects, so it has received widespread attention. The mechanisms of action of organometallic ruthenium antitumor compounds and cisplatin are not exactly the same, but they both use DNA as the ultimate target and belong...
